Subject: [PATCH 05/13] net: dsa: mt7530: move SGMII PCS creation to
mt7530_probe function
Move creating the SGMII PCS from mt753x_setup() to the more appropriate
mt7530_probe() function.
This is done also in preparation of moving all functions related to
MDIO-connected MT753x switches to a separate module.
